Length Scale of Dynamic Heterogeneities at the Glass Transition Determined by Multidimensional Nuclear Magnetic Resonance
Open accessAbstract
We directly measure the equilibrium length scale of dynamic heterogeneities close to the glass transition by means of a new multidimensional NMR experiment. The spatial information is gained from a proton spin diffusion experiment combined with two 2D ${}^{13}\mathrm{C}$ exchange sequences via appropriate back and forth transfer of magnetization between ${}^{13}\mathrm{C}$ and ${}^{1}\mathrm{H}$ spins. For poly(vinyl acetate) at 10 K above the glass transition we detected a length scale of $3\ifmmode\pm\else\textpm\fi{}1\mathrm{nm}$.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
